The maternal relationship between Josephine White and her son Charles Edward Vining is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MP.

The segmental (via DNA segment triangulation) and total DNA shared between MP and other confirmed descendants of Abel Allen White/Elizabeth Peck is consistent with the expected ranges for their respective relationships. Since MP descends from Abel Allen White/Elizabeth Peck through Josephine White and her son Charles Edward Vining, the presence of significant shared DNA between MP and other known descendants of Abel Allen White/Elizabeth Peck validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Abel Allen White/Elizabeth Peck through Josephine White to Charles Edward Vining, and ultimately to MP, confirming this direct ancestral connection through multiple generations.
